MACHINE FOR FORMING STORAGE-BATTERY PLATES;

To all whom it may concern:

Be it known that I, FRANK ENcnL. a citi zen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Machines for Forming Storage-Battery Plates, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanye ing drawing, forming a part of this specification.

' My invention relates to a machine for manufacturing storage battery plates.

' The object of my invention is to .produce a mechanism adapted to machine a plate which when completed, will have a plurality of fine, uniform, compact ribs covering substantially the entire surface of the plate and increasing its superficial area enormously.

In prior attempts to increase the superficial area of the plate, various methods have been adopted all of which have serious disadvantages. One of the early methods was to cast a plate having fins or ribs there on, but the density of the material in this case was not sufiicient, nor was it uniform, and flaws occurred frequently throughout the plate. Another method was to spin the plates by forcing rapidly revolving disks or knivesagainst the surface. This process tended to microscopically disruptor tear the surface of the metal along ltlhe sides of the out, thus subjecting the plate to the unequal attack of the electrolyte. Still an other method was to plow or groove the plate, with somewhat the same disadvantages'of tearing open the surface of the metal along the out. Another method was to subject the plate to a rolling action which produced grooves and at the same time was intended to condense and render more commetal of the blank, particularly near the surface. One of the disadvantageous features of this rolling process,

however, was that the upper layer or stratum of metal was pushed ahead or crowded along by the advancing roll, and being thus displaced with reference to the metal immediately' under-it, there was a tendency to disrupt the metal near. the surface of theplate, rather than to condense it uniformly.

Another disadvantage of the rolling process was the difficulty of forming very tine uni form grooves by a roll having thereon a Specification of Letters Patent.

.over their entire surface.

plurality of projections or ribs, in some cases about twenty-five to an inch, which ribs, in rolling back and forth over the blank were lifted up at! one point and then later were expected to fit into the .Same.

groove on the return stroke, to roll it deeper.

Where such fine fins are used, it is very diff ficult to construct a machine having rolls which accurately match with the grooves upon repeated trips back and forth over the metal.

The present machine oyercomes these disadvantages by formingfa platehavlng very and which are uniformly dense and compact I have adopted in practice, and which is very successful, is to work or embed groups or gangs of small blades in the surface of the metal blank, these gangs being applied to one or both sides of the blank andforced 'there nto by pressure, while accompanied by a slight rocking motion to facilitate their I insertion, to smooth, compress, and render compact all portions of the metal thereabout, and to permit the blades to be readily 8'0 withdrawn from the blank when the work is finished.

While a machine for manufacturing a plate having the desired characteristics may be constructed in a variety of ways, I have selected for the purpose of illustration, a simple and practical embodiment of my invention as shown in, the accompanyin drawings, in which Figure l is a s1 end elevation,Fig. 4 is a partial longitu dinal section,Fig. 5 is a perspective view of one of the blades,-Fig. 6 is .a detail of a is a detail of a former bladeand-spac'er,

T he machine selected for illustration, comprises a bas c 1, supporting shaft 2, at one end, driven by pulley 3, through reduction gears ll and 5. It is understood, of course, that any suitable form of drive may be used. lhe base also carries four upright members {3, having bearing caps 7, adjustable with respect thereto by means of screws 8, at one end thereof, the other end being secured by any suitable means such as pin 9.

A frame or blank holder 10, is slidably supported about the middle of the uprights l3 and is adapted to carry a lead blank 11 from which the finished plate is to be made.

This frame slides in ways formed by lugs 12,

and accordingly may be readily withdrawn from the machine. Of course it may be sup ported by other suitable means. The blank is held snugly iu the frame and supported by a lip 13, or it may be secured by any suita le clamping means.

lhe essential parts of the machine which coiiperate with the blank to form it in the manner described above, are a series of gangs of small blades whose working edges, when applied to the plate, cover substantially the entire area of a side, a mounting or support for all the blades on one side of the blank and to which the blades are pivoted in rows or gangs, means for advancing the mounting toward the blank either continuously or intermittently, to embed the blades in the blank, and mechanism for imptu'tinga slight reciprocation to the mountmg to rock all the blades during their adtall van-2e, a s described more in detail later.

Inasmuch astwo sets of blades or formers are illustrated, one above and one below the plate, which sets are substantially alike, it will be necessary to describe only the upper one, except where it differs in some slight detail from the lower. that the blank be held horizontally, as it might be arranged in any convenient position as long as the two sets of formers are mounted so as to imultaneously operate upon its opposite si es. If-it is desired to work only one side of a plate, one set of formers may be omitted and a substantial support or backing for the blank substituted therefor -OWlI1,:',{ to the rocki action and to the fact that a large number of closely alined formers act on the plate simu1taneously, it becomes practical to work one side only if desired? without the plate adhering to the sides of the embedded oscillating It is not essential or distortion of the blank such as would be likely to occur if the attempt were made to roll a ribbed, cylindrical former across one side of the plate.

Referring now to the upper half of the machine, the adjustable bearing caps 7 constitute journals for an eccentric shaft 14, on which is mounted an eccentric cap 15, to which is secured a plate or cross-head 16. The cap 15 may howeverbe advanced by a step by step movement if desired,instend of by a gradual eccentric motion, or any other suitable continuous or intermittent movement may be imparted. The crosshead, as seen particularly in Fig. 8, has at each of the four corners, a depending apron 17, adapted to slide UJOII one of the four parallel upright mem ers 6. Instead of this arrangement, it will be obvious that any suitable group of parallel ays may be provided, which will answer the purpose. The cross-head has beveled portions 18, which constitute a dove-tailcd connection adapted to engage a correspmiding dove-tail on a slide 19. This slide 19 is adapted to reciprocate with respect to the plate .or cross-head l6 and eccentric cap 15, and at the same time to be carried toward or away from the blank by the slight rotary movement of the cap 15 upon the eccentric shaft ll.

Inasmuch as the cross-head 16 is permitted to slide vertically only, in the preferred construction, it must necessarily have a sliding connection with the eccentric cap 15, whose eccentric motion has a horizontal component with reference tosaid cross-head. In. the preferred construction, this connection is secured by bolts 20, secured in the cross-head 16, which bolts slide in elongated slots 21 in the eccentric cap 15, as shown clearly in Figs. 2 and 4.

Depending from the upper slide 19, are links 22, which support the bolts or mandrels 23, upon each of which bolts are clamped the laminated formers consisting of alternate thin blades 24 and washers 25. The blades and washers are held in place by bolts 23". 'lhesebladcs consist preferably of pieces of steel or other suitable material, having in the preferred form, the general outline shown in Figs. 5 and 12, in which the beveled working edge 26 is at right angles with the length of the blade.

This blade is adapted to rock against the working edge, and if during this rocking,

the blade is forced nearer the center of the blank, a convex depression will result, as

shown more clearly in Figs. 12 and 16. The specific mechanism for accomplishing this motion 18 described later, a

As will be seen from Figsrl and 4, each side of the plate is worked on by a series of formers, the exact number depending on the size 6f the plate and other considerations. In the drawings, nine .formers are shown by way of illustration. Each former is built-up as shown in Figs. 10 and 11, by clamping the alternate separators and 'blades 2st between nuts 27 on each end of thesquared endsofwhich are adapted to slide ers used, and the studs'31 in each hole serve vertically between the upright ,members 66, although I do not limit myself to this construction. This spacer has a number of holes corresponding to the number of form-- to maintain the working ends of the formers in fixed spaced relation, While at the the former-oscillates. i

From an inspection of Fig.1Q" it will be seen that there are two spacers 32'-32, one

'same time constituting a pivotaboutwhich for the upper set 'ofnformers, and one for the lower. These spacers are arranged closely together, which arrangement necessitates the'use of a much thicker ,end plate 29 on the'lower former than on the upper.

In Fig. 6 is shown the arrangement by which the upper ends of'the blades are adapted to rock with respect to the slide 19 which carries them and which imparts to their-upper ends a reciprocating motion, causing them 1 to also rock about an axis through the stud 31, shown in Figs. 10, 13 and else'whe'rei The upper ends of the blades 2st fit into the under sideot a rocking bearing 33, having a cylindrical .surface bearing in'a cylindri calgroove in the slide 19. SeeFigs, (3 and 7. It is obvious that as long as the Working edge of the blade 24; is forced against the blank, there will bea thrust against the slide 19, through bearing 33. VVhenthis thrust is removed, however, the bearing will fall from its groove in the slide 19, except forthe' 'detaining links 22. It is evident that two links, or even 0 e link on a side would be sufficient to .hol the entire group of formers in place by virtue of the connecting.

spacing member 32, pivoted to each former.

2II1 the drawings 110W6V6i3ffiV6 links --are shown. 1 i a p From the above description it Will be seen i that if a slight reciprocating motion is given to the Slide 19, the horizontal Working edges 7 of thaformers will rock upon the surfaceof the blank. ,At the same time the spacers 32 will be given a slight vertical reciprocating motion, and this motion will occur whether the slide 19 remains at the same vertical. 1o

height or whetherit is being gradually lowered' by its supporting cross-head 16, forced downward by the eccentric cap 15.

The shaft 2 carriesthe cam 34 working in a reciprocating block 35, which'block gives a rocking motion to the member 36, pivoted at 37, and having oppositely extending arms .38. Links 39connect the ends of these arms with the upper and lower reciprocating slides 1919. It will be clear thatthe oscillating motion of member 36 will produce by means of links 39, simultaneous reciprocation in oppositedirections of theslides In the above description, the action of the upper set of formers only has been, de scribed, but it will be obvious thattheaction of the? lower set of formers'which are arranged the reverse of the upper'setsoas to oppose their thrust, will be substantially identical. It should be noted, however, that the method of regulating the distance between the upper-and lmvereccentric shafts. iswnot identical for each shaft. The upper shaft is adjusted-by turning one regulating screw 8 to raise or lower one end of either upper bearing member 7, the other end being pivoted at9. {The lower shaft may be adjusted by a screw 8 at each end of the lower bearing member 7, although I do not limit myself to the above details.

The adjusting screws may'be of anysuitable construction, the lor n shown.-.1n detail in Figs. 20 and 21 being a practical one.

'Each ad'ustin screw com )riscs an uner and a lower screw-threaded extension. The lower screw-threaded extension htsj in the 'screw threaded open ng in the trame, while the upper screw-threaded extension fits loosely in the opening in the bearing block and is provided with asuitable nut. The screws 'a're rotated by inserting a bar or wrench in the circumferential openings therein, whereby sufficient leverage is obtained to rotate the screws and raise or lower the bearing block. i l

The main shaft 2. carries a bevel gear 40, engaging gear 41 and driving the vertical.

. shaft 12 through a worm and gear reduction 43,544. This verticalshaft drives both eccentric shafts 14.-14, by means of additional worm and gear mechanism 45, 46,- so that the rotation of both eccentric shafts is very slow as compared with-the main driving shaft.

ers'either continuously or intermittenly, may be employed however. i f

It is desirable to provide means for quickly Any suitable means for advancing the form- 5 a retracting the formers after they have con "verted the blank into a finished plate, and

forthis purpose cranks 4:7'.47 are'fastened to each eccentric shaft and the ends of said shafts to be driven in one direction from the main power shaft andalsopermits them to be turned ahead of the driving gears by means of the handle 49 to quickly Withdraw the formers upon the completion of the plate.

The Working blade the preferred form is of general rectangular outline as shown in Fig. 12.- When a blade of this character is forced against and caused to rock upon a blank of lead or other material,.the pressure on the blank is alternately applied and re leased on any small given area, and the corners of the blade work deeper into the metal than the middle portion, producing a recess with a convex inner end, as shown in Fig. 12 and at 51, Fig. 16. This is due to the fact that the radial distance from the axis of rotation to the different points on the Working edge, is not the same for all points. I do not limit myself to this feature, however, as the blades may assume a great variety of forms. l

Although the angle of pressure of the blades against the blank undergoes some vi riation during the rocking of the preferred form of blade, the deviatlon of the line of pressure from the normal is never great enough to disrupt the metal by unduly crowding the outer stratum of the; blank in a longitudinal direction. Furthermore, as the blank has a plurality of closely arranged blades embedded in it, the metal under any one blade cannot suffer much distortion in a longitudinal or lateral direction because of the restricting effect of similar closely adjacent arcas which are being subjected to a a similar pressure. Also the blzules are not withdrawn during the rocking, but each remains in its individual groove, which thus becomes gradually deeper. As a result of all the above, there is practically no tendency of the plat as a whole, to spread in either direction, the displaced metal being worked up in the formof compact fins or ribs.

As seen in Fig. 5, the bevel at the end of the former is a very 'adual one, and as seen further in Fig. 11, the washers do not extcn d far enough to meet the end of the bevel. This arrangement is not necessary, however, as a longer bevel might be used, extending to the lower end of the washers, or longer ushers might be used, extending to the present bevel. The effect of the gradual bevel in either case is to compress the metal between adjacent blades by a wedging action, the in or rib being worked upward still farther and having a squared end in one case and in the other case tapering gradually to the end. It will be understood, of

c'ourse, that'a former of integral structure may be used instead of one built up of laminations, the invention not being limited to any particular details of construction, as regards this feature, or any of the features of the machine selected for illustration only.

The operation of the machine is as follows: The blank holder having been with drawn, a lead blank is placed therein and both members are then slid into the mm chine, with the formers and their supporting parts separated the maximum distance. Power is then applied to the main shaft and a reciprocating motion given to the slides as explained above, Simultaneously the asso sociated parts and the eccentric caps begin to move toward each other gradually as in the preferred construction, due to direct connection between the shafts i l-1 1 and the driving shaft, thus embedding the blades 5 A in the blank. .The effect of the reciprocation of the slides is to give a rocking motion to the working faces of the formers, so that the metal of the blank is gradually I grooved, compressed and condensed under and between the individual blades as they advance, and worked up in the form of uniformly condensed fins between the blades, until the fins meet the washers, after which by embedding the formers stillfar'thcr in the metal. The kllfildll'l" and )IGSSIIIO' b l a: process is continued until the blades have been brought so close together that their workmg edges have almost forced their way 1 through the lead blank, thus giving the desired cross section as shown in Fig..1 i.- It is understood that the so-called working edge is sharp enough to slowly force its Way through the lead but does not cut or'tear the metal. simply pushing it aside, and by compressing it between adjacent beveled blades, condenses it and renders its surface smooth, compact, and homogenous.

lVhen it is desired to provide the plate duced to a very thin membrane which is easily removed.

lt has been found desirable to provide a some sort of lubrication for the blades while they are bemg forced mto the plate. For

this purpose water is satisfactory and may 1 be supplied to the plate in any convenient manner. a

On completion of the plate, the formers may be quickly separated by hand power mechanism as described, by turning theec- I25 centric shafts to separate the eccentric caps and parts carried thereby. whereupon the finished plate is removed from the frame and a new blank is substituted therefor.

It is obvious. that many changes within a still further compression may be secured 95 the scope of the invention as defined in the appended claims, may be madeinthe machine described and further, thatthe'inventi'on is not limited to the structure de; scribed above in detail, as said structure is selected for the purpose of illustration only,
